GLARESHIELD FOR HEADLIGHTS.

Application filed May 10, 1923. Serial! No. 637,976.

To all whom it may concern:

Be it known that 1, PAUL L. WILSON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Glareing had to the accompanying drawings in.

Which- Figure 1 is a central section through aheadlight having my invention applied thereto,

Figure 2 asection on line 22 of Figure 1,

Figure 3 an enlarged fragmentary central section similar to Figure 1 showing a modified form of securing means,

Figure 4 a view similar to Figure 3 showin another form of securing means, and

igure 5 a perspective view of the inclined shielding plates which form a part of my invention.

Referring to the drawings, 1 indicates a casing-of a headlight, 2 the lamp, 3 the reflector, 4 the lens and 5 the rim for securing the lens to the reflector.

' My invention includes a band 6 provided with lugs 7 radiating therefrom adapted to be placed between the lens and rim of the headlight and securely held therebetween, Inclined shielding plates 8 are s aced within the band and secured thereto y any suitable means.- The iri'clination and width of the strip are such that the outer edge 9 of each plate and the inner edge 10 of the lower adjacent plate will intersect a horizontal plane as indicated in dot-and-dash lines at 11 in Figure 1. This arrangement of the plates prevents the light from passing in an upward and a horizontal direction but permits the rays to pass downward to illuminate the road. The shielding plates "are preferably constructed from a stripof metal by cutting notches 12 therein and bending the strips at the notches as shown at 13 in Figure 5. The shielding plates in this bent form are then placed. within the band and held therein by frictional engagement therewith. The shielding plates may be soldered to the band or dipped into a molten mass of low temperature, such as lead, tin, zinc or the like to securely hold the plates to the band.

In Figure 3 I have shown a form of securing means which includes lugs 14: bent upward from the band and secured to the rim 5 by screws 15.

In Figure 4 I have shown a form of securing means which includes strip springs 16 secured to the band 6 by rivets. 17 The springs embrace the rim and casing and hold the glare shield in position. In all other respects the construction in Figures 3 and 4 is similar to that shown in Figures 1, 2 and5 and I have therefore given corresporiding parts similar reference characters.

To apply my improved glare shield to a headlight, the rim 5 is removed from the headlight and the glare shield placed within the opening of the rim so that the radiating parts or lugs 7 will be within the rim. The lens is placed against the glare shield within the rim and the rim put on the headlight in the usual manner.

By providing a glare shield having the shielding plates of such a width and disposed at an incline so that the outer. edgeof each plate and the inner edge of the lower adjacent plate will intersect a horizontal plane, the glare from the headli ht isobstructed to an observer above a orizontal plane with the headlight while in a downward direction toward the road, the light passes freely between the plates practically unobstructed, thus illuminating the road in the usual manner. By making the shielding plates comparatively wide so that'they will project beyond the band 6, the road'may be illuminated a considerable distance from the headlight without throwing the glare to an observer at that distance.

If desired, a flange may be provided around the band instead of the lugs for securing purposes, but I have found that the lugs make a lighter structure and serve as well.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A glare shield for' headlights including a band; a strip of metal bent to form inclined shielding plates within the band and having their inner edges flush with the inner edge of the band and their entire outer edges projecting equal distances beyond the outer edge of the band, the outer edge of each plate and the inner edge of the lower adjacent plate intersecting a horizontal plane, andmeans for securing the band to the headlight whereby the inner edges of the plates will abut the lens of the headlight.

In testimony whereof I have signed my name to this specification in the presence of 20 two subscribing witnesses.
